On the mechanism of T4c(6900) tetraquark production
We discuss the production mechanism of a new state, a putative fully charm tetraquark, observed recently by the LHCb at M=6.9 GeV in the J/ψJ/ψ channel. Both single parton scattering (SPS) and double parton scattering (DPS) mechanisms are considered. We calculate the distribution in the invariant ma...
